Adding phone numbers to the MMI

[Hoppy1888]

Hi, I have connected my iPhone to the MMI via blue tooth which works well but how do I transfer my contacts onto the built in hard drive? 

I want to be able to select the voice command and say call Sarah for example and for the call to connect. At the minute the car simply tells me no numbers are stored.

I can receive calls no problem or call out using the actual phone to dial the contact but that's not ideal when driving or when it's in my pocket etc. 

Thanks in advance, hope this makes sense.
